Tiny Predictive Fan Failure Detector
Features General Description Fan Wear-Out Detection for 2-Wire
Linear-Controlled Fans Replacement System for 3-Wire Fans Fan Alert Signal when Fan Speed is below
Programmed Threshold CLEAR Capability for Eliminating False Alarm Low Operating Current, 90 ВµA (typ.) VDD Range 3.0V to 5.5V Available in a 6-Pin SOT-23 Package The TC670 is an integrated fan speed sensor that
predicts and/or detects fan failure, preventing thermal
damage to systems with cooling fans. When the fan
speed falls below a user-specified level, the TC670
asserts an ALERT signal. With this design, a critical
minimum fan speed is determined by the user. The fan
alert level is then set with a resistor divider on the
THRESHOLD pin (Pin 1) of the TC670. When the
minimum fan speed is reached, the ALERT pin (Pin 5)
changes from a digital high to low. This failure detection
works with all linear-controlled 2-wire fans. The TC670
eliminates the need for 3-wire fan solutions. Applications A CLEAR option can be used to reset the ALERT signal, allowing the flexibility of connecting the ALERT
output of the TC670 with other ALERT/FAULT interrupts in the system. This feature can be implemented
so that false fan fault conditions do not initiate system
shutdown. Protection for Linear-Controlled Fans
